If you are familiar with the product backtracker, (at around 50 bucks) you might dig this app.

It's perfect for PPG. And just dead simple. It only has two buttons - set your waypoint - and where is the waypoint. That and a big, line of sight directional arrow pointing where you want to go. It also tells your distance. Great for PPG. If you fly in unfamiliar country, and you suddenly find yourself at a loss t say where your LZ is, this app will point to it, and give you the distance. No scrolling, no thinking, no fuss.

RESCUE LOCATOR/CONTACT $2.99

www.rescue-app.com

I haven't bought this, or checked it out, but it might be worth looking into, if you haven't invested in a real Personal Locator Beacon like the FASTFIND. (Which some people who fly alone should. See my review of FASTFIND VS SPOT)

SKYKOGGER $5.99

http://www.skywind.eu/SkyLogger/EN/index.htmlSkyLogger obtains the geodetic positions of the pilot during the flight and stores the data. Furthermore, the pilot is able to see during the flight the elapsed time, the distance to the take-off as well as the current ground speed and climb rate. A compass rose is indicating the current flight direction.

GENERALLY USEFUL AND PPG APPROPRIATE

VOICE TO TEXThttp://www.nfinityinc.com/quickvoiceip.html

While I've never tried it from the air, it would probably work. This quick voice app will act as a digital tape recorder. Then you can click on an email address, and it will send them a text transcript of the message, as well as an attachment with the voice. Not instant, it can take ten minutes or more to fulfill, but no typing with your thumbs.

VIRTUAL FLASHLIGHThttp://appshopper.com/utilities/iflashlight

Turns the LED light built into the camera into a quite powerful flashlight with a strobe option as well. Burns battery power, but useful.

If your first aid isn't up to scratch, or rusty, you can always use the phone to call 911, and read the appropriate pages to help out. First aid is better delayed a minute or two, than not applied at all. And the life you save may be mine.

STOPWATCH

Easy app, and free.

MOBILE KNOT GUIDE

Replacing a line? Have another look at your double sheet bend. An easy knot unless you do it "backwards" and then its pretty much useless.
